If you’re using Overleaf, it’s usually best to upload a copy of the class to your project. Please remember that the
file must be called msu-thesis.cls. Naming it something different will cause it not to be found, and an older
version will be loaded. Additionally, since Overleaf preserves the TeX Live year that you first opened the
project, it’s a good idea to change to the most recent TeX Live year that the site offers. You can
do this by clicking on the Menu icon in the editor and then selecting the most recent TeX Live
version.
